Thanks! I have read about people doing roughly the same thing, but using several coats of thinned urethane spar varnish instead of film for the final protective coating. IDK if this is any better than the clear coat you used though.
I wish automakers would just use glass for the headlights. The few pounds of extra weight would be worth it in long-term satisfaction, I think.
